This app simply displays a rolling average for health data or any other type of data you choose to enter. However, it does NOT collect any personal data or have any registration process, and any health or other data entered into the app is stored locally on your device and nowhere else. The app allows you to delete this data at any time via the options. You therefore have complete control over all your health and other data, as well as complete privacy and anonymity when using the app since no-one else can see anything about you or your data.
